Edison Power Distribution Blocks
Short-Circuit Current Rated Power
Distribution Blocks
We offer distinctly different styles of short-circuit current rated
Power Distribution Blocks and Terminal Blocks to match different application needs.
1) Enclosed style or Open style
2) UL1953 Listed power distribution blocks or UL1059 Recognized
terminal blocks, that have different minimum spacing requirements.
The table below can assist in the selection of the correct series
for your application requirements.
Why are these important?
Assembly short-circuit current ratings (SCCRs) are now required in the 2005 NEC® and UL508A Listed industrial control panels.
Marking the SCCR on:
Industrial Control Panels (NEC® 409.110)
Industrial Machinery Electrical Panels (NEC® 670.3(A))
HVAC equipment (NEC® 440.4(B)
The above sections are now required by the National Electrical Code. Power Distribution Blocks or Terminal Blocks not
marked with an SCCR are typically one of the weakest links
and may limit an assembly to no more than 10 kA SCCR per
Table SB4.1 UL508A. The EPDB series and HPB series Power
Distribution Blocks have increased spacing required where
used in feeder circuits in equipment listed to UL508A. The PB
series UL1059 Terminal Blocks must be evaluated for proper
spacing. Also, for building wiring systems, the EPDB series and
HPB series power distribution blocks can be used to meet the
2005 NEC® requirements in section 376.56(B) for power distribution blocks in wireways.

EPDB Series Edison Finger-Safe
Power Distribution Blocks
Finger-safe
distribution blocks
Features
Use Finger-safe Power Distribution
Blocks to manage your power distribution needs, from splitting primary power
circuits into a variety of branch circuits to
providing a fixed junction tap-off point.
The modular design allows the end user
to select and configure the number of
poles required by each application.
These blocks are engineered to allow
copper conductors and maintain an
SCCR rating of 200kA. These features
make these blocks the perfect solution
to today’s power circuit wiring requirements.
